- To all whom it may concern:

Be it known that I, R BERT R. RoBERTs, of Vex-million, county of Edgar and State of Illinois, have invented an Improved Elevator for Vehicles.

The following description, taken in connection with the accompanying plate of drawings hereinafter referred to, forms a full and exact specification, wherein are set forth the nature and principles of the invention, by which the same may be distinguished from others of a similar class, together with such parts thereof as are claimed as new and are desired to be secured by Letters Patent of theUnited States.

My invention relates to that class of devices which are made usev of for elevating articles upon vehicles; and the nature thereof consists in certain improvements in the construction of the same, and novel combinations of the parts thereof, hereinafter shown and described.

In the accompanying plate of drawings, in which corresponding parts are designated by the same letters, the figure is a perspective view.

A designates the frame of the Vehicle to which the elevator is applied. b designates a standard having a notch out in the bottom thereof in such a manner as to allow it to rest partially upon the said frame and form a projecting end, which is held to the frame by the band 0. The said standard is secured in the bar H may be raised, lowered, or held in any position.

I am aware that single links, similar in construction and operation to the link P, have.

heretofore been used. I am also aware that my invention consists of a combination of parts, each of which, individually considered, is old.

Having thus described my invention, I 1

claim- The portable lifting mechanism described, consisting of the standard b, band 0, rods d, staples 0, upright bar H, provided withnotches h, links p,.swivel I, and lever K, ail combined and arranged as and for the purposes described.
